基于GVA的互联网区分服务定价模型

在Diff-Serv(区分服务)机制的基础上,研究互联网的区分服务定价问题．通过导入广义第二价格拍卖(Generalized Vickrey Auction,GVA),构造了基于Diff—Serv的互联网区分服务定价模型．该模型能够有效解决Internet拥塞问题,促进网络资源的合理利用。     

MCHOKeM algorithm with assured bandwidth allocation in DiffServ networks

An active queue management (AQM) algorithm called MCHOKeM is presented, which is borrowed from CHOKeW that draws multi-packets at random from the buffer, the multi-packets are compared with an arriving packet and abandoned if they are from the same flow. But MCHOKeM uses multiple virtual queues for different priority packets and enhances the drawing function by adjusting the maximum number of draws based on the current status of virtual queue length. The number of parameters that MCHOKeM needs to maintain is determined by the number of priority levels being supported by the router, which usually has a small limited value. In order to explain the features of MCHOKeM, an analytical model is used. A series of simulation tests to evaluate the performance are given.
